The base body is provided with an extendible member. A driving member controls the extendible member for reciprocal movement in a longitudinal direction on the base body. The extendible member is also provided with an electricity-conducting assembly, which includes a conduction member and an electricity-conducting member. As such, to do charging, the driving member controls the extendible member to extend in the longitudinal direction and the electricity-conducting member is collaboratively operating with a charging seat to achieve electrical transmission of electricity through the electricity-conducting member and the conduction member for carrying out charging to a battery of the electrical vehicle. Further, the charging can be performed while traveling.

TECHNICAL FIELD OF THE INVENTION

The present invention relates to a charging device, and more particularly to a concealed charging device of an electrical vehicle and a method thereof, in which the charging device is concealed in a vehicle body of the electrical vehicle so as to maintain the original aesthetics of the vehicle body and also to enhance the cruising endurability of the electrical vehicle.

DESCRIPTION OF THE PRIOR ART

An electrical vehicle that is powered solely with electricity is commonly referred to as a battery electrical vehicle that is one powered by a fully charged battery. A vehicle that is driven by an electrical machine is often referred to as an electrical vehicle in the media, due to the electricity of the battery is supplied from an external electricity source. The electrical vehicles do not emit exhaust on the roads and do not cause pollution to the atmosphere on the roads. Such an advantage is the primary reason that the electrical vehicles are promoted in all the countries around the world. Further, the electrical vehicles have an excellent capability of quickly speeding up at a low speed condition, and some working vehicles that require frequent stopping and moving again, such as buses and garbage trucks operating with high torque, have been substituted with electrical motors to improve efficiency. Different from fuel-combusting vehicles that require idling when stopping movement in order to prevent engine shutdown, the battery electrical vehicles allow the electrical machine to be completely shut down when stopping movement, and consuming no energy at all. This also effectively prevents vehicle jamming and waste of energy.

The electrical vehicles suffer a major problem concerning cruising endurability. In case that electricity runs out during travel, the electrical vehicle has to travel to a charging station to park and be charged. For the existing environment and technology of electrical charging, the number of charging stations is still small. The electrical vehicle, even when reaching a charging station, must be queued in line for charging. Even there is no need for queuing, the charging time is also a problem. This would affect the milage time and is inconvenient for the electrical vehicle owners.

In view of this, to improve the problems associated with charging of electrical vehicles, manufacturers proposed a charging device that enables charging to proceed during travel of an electrical vehicle. For example, Chinese Patent CN107054365 B provides a method for operating a motor vehicle, a controller of a motor vehicle, and a motor vehicle. The patent resolves the problem of running out of electricity during travel of an electrical vehicle, allowing the electrical vehicle to be charged simultaneously with traveling of the electrical vehicle, achieving an advantage of saving mileage time. Further, Taiwan Patent 1428845 provides an on-road charging system and method. The patent proposes a charging system embedded in a road surface, and this also resolve the issue of running out of electricity during traveling of an electrical vehicle.

However, the above-mentioned patent that provides a method for operating a motor vehicle, a controller of a motor vehicle, and a motor vehicle suffers the following problems in use and further improvements are necessary;

Firstly, although the problem of charging can be resolved, a charging arm provided therein is expanded in a fan shape for being disposed on a chassis of an electrical vehicle, so that a large area is necessary for installation, making it occupying a large space and deficient in concealability.

Secondly, due to being installed on an outside of a body of an electrical vehicle to occupy a large area and being expanded in a fan shape, it is not good for outside appearance of the electrical vehicle, and would deteriorate the overall aesthetics of the vehicle body.

Thirdly, due to being installed in a manner of being exposed outside the body of the electrical vehicle, it could be easily damaged and may cause risk of electric leakage.

Fourthly, due to the number of charging points being small today, queuing is necessary for doing charging, and this wastes time.

Fifthly, rainwater accumulated on a road surface in raining days would cause potential risk of electrical shocks due to the technology of burying charging stations in the earth, and this might be extremely dangerous.

SUMMARY OF THE INVENTION

An objective of the present invention is to provide a concealed charging device of an electrical vehicle and a method thereof. The main structure comprises a base body, at least one extendible member, an electricity-conducting assembly, and a driving member. The base body is arranged on the electrical vehicle, and the extendible member is arranged on the base body, so that the driving member that is arranged on the electrical vehicle controls the extendible member to reciprocally move in a longitudinal direction on the base body. Further, the electricity-conducting assembly is arranged on the extendible member, the electricity-conducting assembly comprises a conduction member electrically connected with a battery of the electrical vehicle and at least one electricity-conducting member arranged at an end of the extendible member and electrically connected with the conduction member. When the extendible member is in an extended state, the electricity-conducting member is away from the base body. As such, when the battery of the electrical vehicle is still of a sufficient amount of electricity, the driving member does not drive the extendible member to extend on the base body, so that at this moment, the electricity-conducting member is located at one side of the base body. When the battery of the electrical vehicle is running short of electricity, the driver may activate the driving member to allow the driving member to drive the extendible member to move outward in the longitudinal direction on the base body, and the electricity-conducting member is moved away from the base body, and as such an extension operation for performing charging is completed. Further, the base body can be arranged on the chassis of the electrical vehicle or in the interior of a bump, which is generally not noticed by a user, so as to achieve an effect of concealing.

Following the above-described techniques, the problems that the charging arm has to expand in a fan shape and has to be disposed on a chassis of an electrical vehicle found in the prior art patent of a method for operating a motor vehicle, a controller of a motor vehicle, and a motor vehicle, making it necessary to use a large area for installation and occupying quite a space and providing no concealability, and making the overall aesthetics poor resulting from no concealability, and suffering risk of electrical leakage can be overcome, and thus, the present invention may achieve practical advantages of being capable of charging without parking, effectively resolving shortage of electricity resulting from traffic congestion, and effectively prolonging travel distance, occupying no space for the entirety thereof and featuring concealability, low cost, operability in raining days, no concern of safety, and no damage to the aesthetics of the electrical vehicle.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIG. 1 , which is a perspective view, in a see-through form, showing the present invention is arranged as being concealed inside a rear bumper of an electrical vehicle, it can be clearly seen in the drawing that the present invention comprises:

a base body 1, which is arranged, in a concealed manner, in an electrical vehicle 4, the electrical vehicle 4 having a vehicle body 41 that has a side in which a through opening 411 is formed;

at least one extendible member 11, which is arranged on the base body 1 and is reciprocally moveable in a longitudinal direction on the base body 1;

an electricity-conducting assembly 12, which is arranged on the extendible member 11, the electricity-conducting assembly 12 comprising a conduction member 121 electrically connected with a battery 42 of the electrical vehicle 4 and at least one electricity-conducting member 122 arranged at an end of the extendible member 11 and electrically connected with the conduction member 121, wherein in a contracted state of the extendible member 11, the electricity-conducting member 122 is received in the through opening 411, and in an extended state of the extendible member 11, the electricity-conducting member 122 is away from the through opening 411; and

a driving member 2, which is arranged on the electrical vehicle 4 and is electrically connected with the extendible member 11 to control the reciprocal movement of the extendible member 11 in the longitudinal direction on the base body 1.

In the above, the base body 1 and the extendible member 11 of the instant embodiment are arranged to combine with the driving member 2 to form an electrically-powered extendible member, but not limited thereto, and may alternatively be arranged as a pneumatic rod.

In the above, a rear bumper of the electrical vehicle 4 is taken as an example for the vehicle body 41 in the instant embodiment.

In the above, an electrical wire is taken as an example for the conduction member 121 in the instant embodiment.

In the above, electromagnetic coil induction is taken as an example for the electricity-conducting member 122 in the instant embodiment.

In the above, an electrical motor is taken as an example for the driving member 2 in the instant embodiment, and the base body 1 comprises, as being arranged therein, a screw rod 14 fixedly connected to the driving member 2 and a moving block 15 screwed on the screw rod 14, the moving block 15 being fixedly connected to the extendible member 11.

As such, since there is commonly a space present in the rear bumper of the electrical vehicle 4, the invention can be directly installed in the space of the rear bumper of the electrical vehicle 4, so that a driver, when making an observation from any side of the electrical vehicle 4, does not see the concealed charging device of the invention. Further, in a condition that the extendible member 11 is not activated, the electricity-conducting member 122 is located in the through opening 411, and the electricity-conducting member 122 has an outside surface that is generally set in flush with the vehicle body 41, so that excellent concealment is achieved and, also, excellent overall aesthetics can be possessed.

With simultaneous reference to FIGS. 1-4 , which are, respectively, a perspective view, in a see-through form, showing the present invention is arranged as being concealed inside a rear bumper of an electrical vehicle, a perspective view showing an extendible member of the present invention is being extended, a side elevational view showing an electricity-conducting member of the present invention is being connected to a charging seat, and a perspective view showing an electrical vehicle is being charged during travel according to the present invention, it can be clearly seen in the drawings that the electricity-conducting member 122 as described in the instant embodiment is electrically connectable with a charging seat 3. The charging seat 3 comprises a charging space 31 in the form of a trough or recess. Further, in the instant embodiment, being arranged on a guard rail at a road side is taken as an example for the charging seat 3, meaning the charging seat 3 is integrated with the road-side guard rail and can be installed at a turnout of a rod. In the instant embodiment, a highway can be taken as an example for the road, or alternatively, other types of speedway may be used instead. As such, when the electrical vehicle 4 is travelling on the highway and is going to run out of electricity, the driver may operate the electrical vehicle 4 to move into the turnout of the highway and activates the driving member 2 to drive the screw rod 14, so that the screw rod 14 rotates and also moves the moving block 15 out to have the moving block 15 in turn move the extendible member 11 outward for conducting an extension operation, where the extension direction, by taking a reference to the base body 1, is moving in the longitudinal direction. At this moment, the electricity-conducting member 122 of the electricity-conducting assembly 12 moves away from the through opening 411, allowing the extendible member 11 to extend out for a predetermined length and then stop the extension operation. Afterwards, the driver introduces the electricity-conducting member 122 into the charging space 31 of the charging seat 3 to allow electricity to be generated through electromagnetic induction, and the electricity so generated is transmitted through the conduction member 121 into the battery 42 of the electrical vehicle 4 for implementing a charging operation to thereby help extend the travel distance. Further, since the charging seat 3 is integrated with the guard rail and is not arranged in a road surface, when water accumulates in a raining day, there is no risk of electrical shock, exhibiting extremely high degree of safety. Further, when the driver drives the electrical vehicle 4 out of the turnout, the electricity-conducting member 122 is simultaneously moved away from the charging space 31, and the driving member 2 is operated to contract the extendible member 11 to make the electricity-conducting member 122 received into the through opening 411, thereby completing a stowing operation. Further, when the extendible member 11 extends, deformation may occur on the extendible member 11 due to wind resistance resulting from a traveling speed of the electrical vehicle 4; however, the extendible member 11 can be made of a material of one of glass fiber, carbon fiber, or nanometer boron fiber, and titanium alloy, all featuring extendibility and flexibility. As such, the extendible member 11 of the invention may be just like a fishing rod, which is not easily broken or ruptured.

Referring to FIG. 5 , which is a perspective view showing an electrical vehicle is being charged during traffic congestion according to the present invention, it can be clearly seen in the drawing that when the driver drives the electrical vehicle 4 in a traffic congestion on a highway, the electrical vehicle 4 can be driven into a turnout and the extendible member 11 is extended to have the electricity-conducting member 122 connected to and operating with the charging seat 3 to generate electricity. In other words, although the traffic congestion makes it not possible to have the electrical vehicle 4 moving fast, the operation time between the electricity-conducting member 122 and the charging seat 3 is thus extended to have more electricity charged into the electrical vehicle 4 to further extend the travel time thereby effectively resolving the issue of driver's panic due to shortage of electricity. Other details concerning operative relationships among the through opening, the extendible member 11, the electricity-conducting assembly, and the driving member are similar to what described above, and repeated description will be omitted here.

Referring to FIG. 6 , which is a schematic view showing an embodiment of a charging station installed at an interchange according to the present invention, it can be clearly seen in the drawing that in addition to being arranged at a turnout of a highway, the charging seat 3 may be instead arranged on a guard rail of an interchange of a highway to allow the electrical vehicle 4 to do charging even when driving into or out of a rest area in order to further extend the travel distance.

Referring to FIG. 7 , which is a schematic view showing an embodiment of a charging station installed in a parking lot according to the present invention, it can be clearly seen in the drawing that in addition to being arranged at a turnout of a highway or on a guard rail of an interchange, the charging seat 3 a may be instead arranged in a parking lot 5 a in the form of an upright charging pile, so that a driver, after having parked the electrical vehicle 4 a in a parking space, may extend the extendible member 11 a to have the electricity-conducting member connected to the charging seat 3 a for operation together to generate electricity, achieving an effect of charging all the time even when the driver is taking a rest, this being extremely convenient. Other details concerning operative relationships among the through opening, the extendible member 11 a, the electricity-conducting assembly, and the driving member are similar to what described above, and repeated description will be omitted here.

Referring to FIG. 8 , which is a perspective view, in a see-through form, showing the present invention is arranged as being concealed in a central side tread board of an electrical vehicle according to the present invention, it can be clearly seen in the drawing that in addition to being installed in the rear bumper of the electrical vehicle 4 b the rear bumper, the invention can also be arranged in a central side tread board of the electrical vehicle 4 b. The central side tread board is also a part of the vehicle body 41 b of the electrical vehicle 4 b, and thus, the through opening can be formed in the side tread board to allow the electricity-conducting member 122 b to be received in the through opening, so that compared to being arranged inside the rear bumper, a similar effect of excellent concealment can also be achieved, making it hard to identify the invention either from a lateral side or a rear side of the vehicle, exhibiting an excellent effect of aesthetics.

Referring to FIG. 9 , which is a perspective view, in a see-through form, showing the present invention is arranged as being concealed inside a front bumper of an electrical vehicle, it can be clearly seen in the drawing that in addition to being arranged in the rear bumper and the side tread board of the electrical vehicle 4 c, the invention can also be arranged inside a front bumper of the vehicle body 41 c of the electrical vehicle 4 c. This also achieves an effect of excellent concealment and does not destroy the overall aesthetics of the outside appearance of the electrical vehicle 4 c.

As such, when the driven intends to make charging, in addition to extending the extendible member 11 d, a motor 111 d that is arranged on the extendible member 11 d is further employed to electrically connect with and drive the linkage 1222 d for performing an ascending operation, so that during the ascending of the linkage 1222 d, the motor 111 d drives the first link 12221 d and the second link 12222 d to rotate upward and causes the third link 12223 d to move upward, in a balanced manner, thereby making the conductors 1223 d expand in upward and downward direction to collaboratively operate with the charging seat 3 d to transfer electricity. When the extendible member 11 d contracts back into the vehicle body 41 d, the decoration plate 6 d is received in the through opening, and the decoration plate 6 d is of the same color as the vehicle body 41 d, so that the integrity of the vehicle body 41 d is kept when being observed from outside, achieving an effect of concealment.

The base body 1 n is provided with the extendible member 11 n, and a driving member 2 n is employed to control the extendible member 11 n to do a reciprocal movement on the base body 1 n in the longitudinal direction. Further, the extendible member 11 n is provided with the electricity-conducting assembly 12 n, and the electricity-conducting assembly 12 n comprises the conduction member 121 n that is electrically connected with the battery of the electrical vehicle 4 n and at least one electricity-conducting member 122 n arranged on an end of the extendible member 11 n and electrically connected with the conduction member 121 n. To charge, the following steps are performed for performing charging:

Thus, the key techniques based on which the concealed charging device of an electrical vehicle and a method thereof according to the present invention improve the prior art are as follows:

Firstly, the invention provides an arrangement of a through opening 411 in a vehicle body 41 to allow various mechanisms, including a base body 1 and an extendible member 11, to be readily receive and concealed inside the vehicle body 41, with an electricity-conducting member 122 being structured to have an outside shape completely corresponding to the through opening 411, so that observation made from outside of the surface of the electrical vehicle 4 does not easily identify the through opening 411, nor easily noticing such mechanisms including the base body 1 and the extendible member 11, and thus, possessing, as a whole, excellent property of concealment and achieving an advantage of extreme aesthetics.

Secondly, the charging seat 3 is made in perfect combination with a road-side guard rail so that during movement, the electrical vehicle 4 can still be charged, with the driver being not necessarily getting off the vehicle for operation, thereby effectively prolonging the travel distance of the electrical vehicle 4, and also help resolving the issue of electricity shortage for the electrical vehicle 4 in a traffic congestion to thereby releasing the driver's panic.
